"And he came next morning and bought one?" asked the detective.

"I told Mr. Eldrick that," said Murgatroyd, a little sullenly.

"How much did it cost?" inquired Byner.

"Eight pound ten," replied Murgatroyd. "Usual price."

"What did he pay for it in?" continued Prydale.

"He gave me a ten-pound note and I gave him thirty shillings change," answered Murgatroyd.

"Just so," assented Prydale. "Now what line might that be by?"

Murgatroyd was becoming uneasy under all these questions, and his uneasiness was deepened by the way in which both his visitors watched him. He was a man who would have been a bad witness in any case—nervous, ill at ease, suspicious, inclined to boggle—and in this instance he was being forced to invent answers.

"It was—oh, the Royal Atlantic!" he answered at last. "I've an agency for them."

"So I noticed from the bills and placards in your window," observed the detective. "And of course you issue these tickets on their paper—I've seen 'em before. You fill up particulars on a form and a counterfoil, don't you? And you send a copy of those particulars to the Royal Atlantic offices at Liverpool?"
